We are going to work on Spring boot Caching and Security for the project we created in part1 and part2
Continuing with PROJECT: Intro to spring boot project - Part 2 for the User we are going to add security and caching on the application and we will use test and browser to see if the application does what we expect.
Step 1
Import the following dependency
dependencies {
compile 'org.springframework.boot:spring-boot-starter-cache'
}
Step 2
Implement caching for the ’name’ in the “getUser” method, use the right annotation to invoke this 😉, in order to see if something is being served from cache or not we are going to simulate our own delay.
Add this code on your getUser method just before the return statement
try
{
System.out.println("Going to sleep for 5 Secs.. to simulate backend call.");
Thread.sleep(1000*5);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
Use the rest API you created in Part 2 to test your cache
Write an integration test (Testing in which individual software modules are combined and tested as a group) that will call the endpoint which invokes the getUser function four times
Expect output
Without Cache:
Going to sleep for 5 Secs.. to simulate backend call.
Going to sleep for 5 Secs.. to simulate backend call.
Going to sleep for 5 Secs.. to simulate backend call.
Going to sleep for 5 Secs.. to simulate backend call.
With Cache:
Going to sleep for 5 Secs.. to simulate backend call.

Import the following dependency
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-security'
}
Step 1
Override the neccessary functions in the WebSecurityConfigurer class to configure your own username and password
Step 2
Add a test to show that your username and password actually work to override the default one
